Welcome to Add Lib, your Tuesday report on POP! Goes The Charts that’s mad about CHR/Top 40 adds, based on the station data provided by Mediabase 24/7 and Add Board. This week: musical madness before the Fourth of July! Ties! Impacts! More below. It may be hot outside, but it’s hotter on the charts, so let’s dig into those sounds of summer like Add Lib does best:

FOUR SCORE (AND SEVERAL ADDS AGO): With singles from Calvin Harris and DJ Khaled (and their all-star bands) in a tie for this week’s Most Added record at the format, with 46 adds each, we look just below the top spot on the report for showings from a plethora of pop artists. The aggressive battle for adds this week was largely due to the Fourth Of July, which just so happens to fall on a Tuesday this year. So, to all of you program and music directors landing some burgers on the grill a week from now, and maybe some pool or beach action too, we salute you. (Also, where’s my invite?) Let’s highlight four of these potential future hits, all starting out well:

Taking in another 35 adds in its impact week is “Glorious” by Macklemore, which features Skylar Grey. It’s the first single to be released after the rapper’s consciously uncoupling with Ryan Lewis (well, at least for now) and the likely first chart hit for Grey in four years. I’ll take a wild guess and say that you don’t remember “C’mon Let Me Ride”, which featured Eminem, which spent two weeks at #32 in February of that year. (It’s alright, I’d prefer to forget that it exists too.) Besides being the third Most Added title at this format this week, it also stands in the same position on the adds report at Rhythmic radio.

Julia Michaels has no issues with this week’s fourth Most Added song, “Uh Huh”, which starts at 31 stations. It’s the follow-up to “Issues”, which reached a new peak of #4 last week. This one is not a hot B2K cover, but their song called “Uh Huh” peaked at #22 for three weeks in May 2002. Michaels was due to release an EP called Nervous System in the spring, though you can obviously see that it’s been delayed since it hasn’t hit digital retailers yet. Whenever it’s out, I’m sure it’ll be great.

Major Lazer and their new backing band, The Mestanics, silently run with “Know No Better” towards a knowledgeable rank for the week. It’s tied for fifth place, receiving another 24 adds. “Run Up” reached #33 at the end of March, and this release is expected to do “better” than that. (Gee, I’m pretty terrible tonight. Ah, well, I have the week off next week!) Their EP of the same name came out earlier this month, and hit the top 100 on the Billboard 200 album chart.

Finally, in the seventh Most Added slot, we find “Go For Broke”, the latest release for Machine Gun Kelly. Kelly’s new song has a featured vocal from James Arthur, who also scored the fourth Most Added single at Hot AC radio yesterday with “Can I Be Him”. This is likely to be Arthur’s last week on the chart with “Say You Won’t Let Go”, a former #5 hit from earlier this month. Kelly’s had a pair of songs from his latest album, Bloom, reach the chart, including the Camila Cabello-assisted “Bad Things”, a two-week #1 from February.
